SHEET COLLECTING, ASSOCIATING, AND FOLDING MACHINE.

Application filed February 28, 1917.

To all 107mm t may concern.'

Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Sheet Collecting, Associating, and Folding Machines, of which the following is a specification.

The object of this invention is to provide novel means for associating eXtra sheets fed from different sources of sheet supply, such,

. for instance, as cover and insert sheets, with a collected and folded group of sheets fed from another source of supply, means preferably being employed for stitching the so associated sheets together and for folding the same.

A practical embodiment of my invention is represented in the accompanying drawings, in Which,

Figure l is a detail longitudinal vertical central section through so much of sheet collecting, associating and folding machine as includes my invention.v

Fig. 2 is a similar section taken just inside the near side frame,

Fig. 3 is a similar section taken just inside the far side frame, and 1 Fig. 4 is a similar section taken just outside the far side frame showing the geared connection between the several parts.

1 designates a source of eXtra sheet supply, such, for instance, as an insert sheet supply. 2 designates a different source of eXtra sheet supply, such, for instance, as a cover sheet supply.

'Ihese sources 1 and 2 are herein shown as feed tables, the table 1 being provided with a movable sheet stop 3 andthe table 2 with a movable sheet stop 4. Y

Rotary cutters 5 and 6, mounted on suitable shafts 7, 8, are arranged to cut a single web or a plurality of superimposed webs,

which pass through the rolls 9, 10, into sheets, which sheets are passed downwardly between the guides 11,12, and between the rotary coacting carriers 13, 14, mounted on shafts 15, 16, respectively. These carriers arel arranged to collect the sheets in groups and impart a transverse fold to the same. In the present instance, the rotary carrier 14; iS. pIQVidGCl with l Set 0f grippers 17 and Specification of Letters Patent. Pata/ted June 10, 1919,

serial N. 151.546.

a folding blade 18, which blade is arranged to coact with the folding jaws 19 on the rotary carrier 13, every two revolutions of the rotary carrier 14.

A rotary associating carrier 21 mounted on the shaft'22 is herein shown as provided with an odd number of sets of grippers 23, three -for instance. Y

A rotary transfer carrier 24 mounted `on a shaft 25 is arranged to feed the eXtra sheetssuccessively from the sources of sheet supply 1, 2, into position to be associated on the associating carrier 21, with the folded group of sheets from the rotary carrier 13. This rotary transfer carrier 24 is shown as having an even number of grippers, two for instance, the grippers 26 being arranged to take the sheets from the source of sheet supply 1, and the grippers 26* being arranged to take the sheets from the source of sheet supply 2."

A stitcher table 27 is arranged to receive the associated sheets where they are stitched transversely of their travel by the coacting parts 28, 29, of two or more stitchers. A movable stop 30 at the outer end of the stitcher table 27 is arranged in position to engage the' advance edges of the associated sheets and hold them momentarily in position for the stitching operation.

Coacting rotary carriers 31, 32, mounted on their respective shafts 33, 34, are provided; the carrier 31 having a set of grippers 35 arranged to take the stitched, associated sheets from the stitcher table 27. rlhis carrier 31 is also provided witha folding blade 36 arrangedA to coact with the foldingY jaws 37 on the rotary carrier 32 for imparting a transverse fold' to the associatedV sheets along their transversely stitched line. Endless carriers 38, 39, serve to carry the associated sheets onto and Off from a stitcher run at the same surface speed, the carrier 21 at la slightly greater surface speed and the carrier 24 at the same .Surface Speed as the carrier 21. The carriers 31 and 32 rotate one revolution to two revolutions of the rotary carrier 14.

A switch 69 is located at the entrance end of the stitcher table 27, which switch is operated from, a' cam 70 on the shaft 33 of the rotary carrier 31 through the connection 71.

A movable cam 72 for opening the grippers 23 at ythe proper intervals to receive the sheet fed from the extra source of sheet supply 1, is controlled by a cam 73 on the shaft 15 of the rotary carrier 13 through the connection 74. Y

A movable cam 75 for releasing` the grippers 23' at the proper intervals to deliver the associated sheets, is controlled by a cam 76 on the shaft 15 of the rotary carrier 13 through ,the connection 77.

The coacting folding mechanism on the carriers 13 and 14 is of the well known floating blade and jaw type, in which the cam 78 controls the blade 18y and the cams 79, 80, 81, control-the jaws 19.

A movable cam 82 controls the grippers 17 of the rotary carrier 14, and a fixed cam 83 controls they grippers 23 of the rotary car'- rier21 at the point where they receive the folded groupsof sheetsv from the rotary earrier 13.

The coacting folding mechanism of the rotary carriers 31, 32, is of the well known flo-ating blade and jaw' type, the operation of the blade 36 being controlled Aby the'cam 84, and the operation of the jaws 37 being controlled bythe cams 85, 86, 87.

The grippers 35 .on the rotary Acarrier 31 are tumbler operated, thel tumbler 88 being controlled by the pins 89, 90. The grippers 35 are opened to release the associated sheets at the time of folding, by the stationary cam 91.V The grippers 26 on the rotary carrier 24 are tumbler operated, their tumbler 92 being operated by the pins 93, 94. The grip-- pers 26* on the rotary carrier 24 are-also f tumbler operated, their tumbler 95 being controlled by the pins 96, 97. The movement ofthe sheet stop 3 is controlled by the cam 98 arranged to engage the sheet stop roller 100, and the movement of the sheet stop 4 is controlled by the cam 101 arrangedv to en- Veo Y to hold1 the sheets in registerl thereonwhen their'grippers are open. f

fA fixed cam 109 opens the grippers 26V to permit' the sheets fed from the eXtra source ofV sheet supply 1,y toA be transferred to the The positively' grippers 23 of the associating carrier 21. A -Xed cam 110 opens the grippers '26* to release the sheets fed from the` extra source of sheet supply 2, for association with the folded group of sheets and the eXtra sheet fed from the source 1. n Y

Mechanism is herein shown asV arranged for association with a transversely oncefolded group of sheets of an insert sheet fed from the source of supply 1, and a cover sheet fed from the source of supply 2, with the insert on one side of the folded group of sheets and the cover on the other side thereof. l

The rolls 9, 10, are arranged to feed one or more webs tothe rotary cutters 5, 6, where sheets are severed from the web or webs and fed through the guides 11,v 12, to the collecting and folding carriers 13, 14. These carriers are, in the present instance, arranged to collect two sheets or two groups of superimposed' sheets and fold the same transversely of their travel onto the rotary carrier 13.

In the meantime, the rotary carrier 24 has taken an insert sheet from the source of supply 1 and fed it to one of the grippers 23 on the associating carrier 21. gripper 23, with its insert reaches al point between the carriers 21 and 13, a folded group of sheets is transferred from the car` rier 13 to the carrier 21 on top of the .insert sheet. As the associated insert and folded group of sheets reach a point between the carriers 24 and 21, a vco-.ver sheet. which has been taken from the source of sheet supply 2 by the grippers 26* is placed on top of they folded groupV of sheets, and the so associated cover, insert and interposed folded group of sheets are then fed forwardly onto the stitche'r table 27, the switch 69 being thrown into position to insure the passage of the insert sheet with the others onto theV said table.

When these associated sheets reach the stop 30, the sheets are stitched transversely of their travel. The stop 30 is then raised and the advance edges of the sheets are grasped by the set of grippers 35 on the rotaryy carrierV 31. The associated sheets are thenl folded olfv along their stitched line, transverse of their travel, onto the rotary carrier 32 and are delivered therefrolnto the delivery mechanism 42, 43.

It is Vobvious that the rotary carriers 13,;

14,.'can handlel single sheets' or a plurality ofv superimposed sheets fed from" the rotary cutters 5, 6, and Vit is also obvious that the rotary carrier 24 can feed onesheet or a' plurality of superimposed sheet-s from each of the different sources of sheet supply 1 and 2, without departing from the spirit and scope of my invention.

Y It is evident that changes maybe resorted to' in the for-m, construction and arrange.
